Abstract

The electrode needle according to the invention has a shaft 4 and at least one active electrode 7 and is distinguished in that the shaft 4 includes a nuclear magnetic resonance-active marker element 15 spatially associated with the active electrode 7. The nuclear magnetic resonance-active marker element can contain ferromagnetic material such as for example iron, cobalt, nickel or steel.
